Description
本発明は、ワイパ装置に関するものである。
The present invention relates to a wiper device.
従来、車両のウインドウガラスを払拭するワイパ装置は、ワイパが連結されるピボット軸と、同ピボット軸を回動自在に支持するピボットホルダとを備えたものがある。このようなワイパ装置は、ピボット軸が、車体の板体(カウルトップパネル)に形成されたピボット孔に挿通された状態で配置される。
Conventionally, there is a wiper device for wiping a window glass of a vehicle, which includes a pivot shaft to which the wiper is connected and a pivot holder that rotatably supports the pivot shaft. Such a wiper device is arranged in a state where the pivot shaft is inserted into a pivot hole formed in a plate body (a cowl top panel) of the vehicle body.
ところで、雨水や洗浄時における水等の液体が、ピボット孔から車体の内部に浸入し、モータや、ピボット軸を回動させるリンク機構の連結部分(例えばボールジョイント)に付着すると、電気的なトラブルやグリス切れ等の問題が生じる虞がある。そのため、ピボットホルダには、ピボット孔から車体の内部に浸入した液体を受け止めて、モータや、リンク機構の連結部分にかからない位置に排出する水受キャップが装着されている。
By the way, if liquid such as rain water or water during washing penetrates into the inside of the vehicle body from the pivot hole and adheres to the connecting part (for example, a ball joint) of the link mechanism that rotates the motor or the pivot shaft, There is a risk of problems such as breakage of grease and the like. For this reason, the pivot holder is provided with a water receiving cap that receives the liquid that has entered the interior of the vehicle body from the pivot hole and discharges the liquid to a position that does not reach the connecting portion of the motor or the link mechanism.
例えば、特許文献1に記載されたワイパ装置では、水受キャップは、樹脂製であり、その筒部がピボットホルダの先端側から同ピボットホルダに外挿され、筒部の内周縁において径方向内側に突出した突部がピボットホルダの基端部外周面に設けられた係合溝に係合することにより、ピボットホルダに対して組み付けられている。ピボットホルダに組み付けられた水受キャップは、係合溝に係合した突部によって、ピボットホルダの先端側への移動並びにピボットホルダに対する周方向の回転が規制される。また、水受キャップは、ピボット孔から車体の内側に浸入した水等の液体を傘部で受け止め、傘部に設けられた排水パイプから当該液体を排水する。
For example, in the wiper device described in Patent Document 1, the water receiving cap is made of resin, and its cylindrical portion is extrapolated to the pivot holder from the distal end side of the pivot holder, and is radially inward at the inner peripheral edge of the cylindrical portion. The protrusion protruding in the direction is engaged with the engagement groove provided on the outer peripheral surface of the base end portion of the pivot holder, and is assembled to the pivot holder. The water receiving cap assembled to the pivot holder is restricted from moving toward the distal end side of the pivot holder and rotating in the circumferential direction with respect to the pivot holder by the protrusion engaged with the engaging groove. Further, the water receiving cap receives a liquid such as water that has entered the inside of the vehicle body from the pivot hole with the umbrella part, and drains the liquid from a drain pipe provided in the umbrella part.
しかしながら、特許文献1に記載されたワイパ装置では、水受キャップの筒部をピボットホルダに外挿する際、筒部の下端部に設けられた突部は、係合溝に係合するまでの間、ピボットホルダの先端部から係合溝までピボットホルダの外周面に擦り付けられることになる。そのため、ピボットホルダとの間の摩擦により突部が削れてしまう虞がある。なお、一般的に、ピボットホルダは金属製である場合が多く、樹脂製の突部は一層削れやすい。樹脂製の突部が削れると、係合溝に対する突部の係止力が弱まってしまい、突部の係合溝への係合が解除されやすくなってしまう。そのため、輸送中の振動等により、ピボットホルダから水受キャップが外れてしまう虞があった。また、ピボットホルダに対して水受キャップが周方向に回転してしまう虞もあった。
However, in the wiper device described in Patent Literature 1, when the tubular portion of the water receiving cap is extrapolated to the pivot holder, the protrusion provided on the lower end portion of the tubular portion is engaged with the engaging groove. Meanwhile, it is rubbed against the outer peripheral surface of the pivot holder from the tip of the pivot holder to the engaging groove. For this reason, the protrusion may be scraped off due to friction with the pivot holder. In general, the pivot holder is often made of metal, and the resin protrusion is more easily scraped. When the resin protrusion is scraped, the locking force of the protrusion with respect to the engagement groove is weakened, and the engagement of the protrusion with the engagement groove is easily released. For this reason, the water receiving cap may be detached from the pivot holder due to vibration during transportation. In addition, the water receiving cap may rotate in the circumferential direction with respect to the pivot holder.
本発明の目的は、ピボットホルダに対する水受キャップの正規の取付状態からの外れをより確実に防止することができるワイパ装置を提供することにある。
An object of the present invention is to provide a wiper device that can more reliably prevent the water receiving cap from being properly attached to the pivot holder.

Furthermore, an annular plate-shaped second washer 52 is disposed between the first washer 51 and the distal end surface of the pivot support portion 21 so as to be inserted into the first pivot shaft 4.
この第2のワッシャ52の内径は、第1ピボット軸4の外径よりも若干大きい。また、第2のワッシャ52の外径は、ピボット支持部21の外径よりも大きく、本実施形態ではボス部41の外径と略等しくなっている。そのため、第2のワッシャ52は、ボス部41の先端面と軸方向X1に対向している。即ち、ボス部41は、軸方向X1に第2のワッシャ52と重なっている。なお、第2のワッシャ52は、第1ピボット軸4に対して相対回転可能である。
The inner diameter of the second washer 52 is slightly larger than the outer diameter of the first pivot shaft 4. Further, the outer diameter of the second washer 52 is larger than the outer diameter of the pivot support portion 21 and is substantially equal to the outer diameter of the boss portion 41 in this embodiment. Therefore, the second washer 52 faces the tip surface of the boss portion 41 in the axial direction X1. In other words, the boss portion 41 overlaps the second washer 52 in the axial direction X1. Note that the second washer 52 can rotate relative to the first pivot shaft 4.
また、本実施形態の第1のワッシャ51は、円環状の歯付きワッシャである。第1のワッシャ51は、ピボット支持部21の先端面との間に第2のワッシャ52が介在されるように、第1ピボット軸4の外周に同第1ピボット軸4の先端側から嵌め込まれている(締着固定されている)。そして、第1のワッシャ51は、第1ピボット軸4に対して、同第1ピボット軸4と一体回転可能、且つ同第1ピボット軸4の先端側へ移動不能に固定されている。また、第1のワッシャ51は、ピボット支持部21の先端面との間に第2のワッシャ52を挟持しており、第2のワッシャ52は、第1のワッシャ51によって第1ピボット軸4の先端側への移動が阻止されている。更に、第2のワッシャ52は、第1のワッシャ51とピボット支持部21とによって軸方向X1に移動不能に配置されている。即ち、第2のワッシャ52は、第1のワッシャ51とピボット支持部21とによって第1ピボット軸4から脱落不能に同第1ピボット軸4の外周に固定されている。
Further, the first washer 51 of the present embodiment is an annular toothed washer. The first washer 51 is fitted on the outer periphery of the first pivot shaft 4 from the distal end side of the first pivot shaft 4 so that the second washer 52 is interposed between the first washer 51 and the distal end surface of the pivot support portion 21. (Fastened and fastened). The first washer 51 is fixed to the first pivot shaft 4 so as to be able to rotate integrally with the first pivot shaft 4 and to the distal end side of the first pivot shaft 4 so as not to move. Further, the first washer 51 sandwiches the second washer 52 between the first washer 51 and the tip end surface of the pivot support portion 21, and the second washer 52 is attached to the first pivot shaft 4 by the first washer 51. Movement to the tip side is blocked. Further, the second washer 52 is disposed so as to be immovable in the axial direction X1 by the first washer 51 and the pivot support portion 21. In other words, the second washer 52 is fixed to the outer periphery of the first pivot shaft 4 by the first washer 51 and the pivot support portion 21 so as not to be detached from the first pivot shaft 4.
なお、図3に示すように、第1ピボット軸4の先端部(第1ピボット軸4における第1のワッシャ51よりも先端側の部分)には、第1ワイパW1のワイパアーム61の基端部がナット62により固定されている。ワイパアーム61の基端部は、その側壁61aが第1ピボット軸4の基端側に向けて周囲を囲繞するように筒状に延出した形状をなしている。そして、側壁61aは、ボス部41の外周で同ボス部41の先端部と第1ピボット軸4の径方向(以下、径方向X3とする)に重なっている。即ち、ピボット支持部21の先端部及びボス部41の先端部は、ワイパアーム61の基端部によって覆われている。
As shown in FIG. 3, the proximal end portion of the wiper arm 61 of the first wiper W1 is provided at the distal end portion of the first pivot shaft 4 (the portion on the distal end side of the first washer 51 in the first pivot shaft 4). Is fixed by a nut 62. The base end portion of the wiper arm 61 has a shape in which the side wall 61 a extends in a cylindrical shape so as to surround the periphery toward the base end side of the first pivot shaft 4. And the side wall 61a has overlapped with the front-end | tip part of the boss | hub part 41 on the outer periphery of the boss | hub part 41, and the radial direction (henceforth radial direction X3) of the 1st pivot shaft 4. FIG. That is, the distal end portion of the pivot support portion 21 and the distal end portion of the boss portion 41 are covered with the proximal end portion of the wiper arm 61.
次に、本実施形態の作用について説明する。
第2のワッシャ52は、第1のワッシャ51とピボット支持部21とによって第1ピボット軸4の外周に固定されている。第1水受キャップ6のボス部41は、第2のワッシャ52と軸方向X1に重なっている。そのため、ピボット支持部21の先端側から第1水受キャップ6が抜けることが、当該第2のワッシャ52によって阻止される。そして、第1水受キャップ6の傘部42に設けられた挿入突起45は、取付脚22の貫通部25に挿入されることにより、周方向X2において同貫通部25に係合している。そのため、貫通部25に挿入された挿入突起45によって、第1ピボットホルダ1に対して第1水受キャップ6が周方向X2に回転することが阻止される。なお、ここで、ボス部41の下端が取付脚22に当接した状態からボス部41の先端が第2のワッシャ52に当接するまでの第1水受キャップ6の移動距離をLとする。言い換えると、距離Lは、ボス部41の下端が取付脚22に当接するときのボス部41の先端と第2のワッシャ52との間の距離である。挿入突起45の傘部42からの突出高さをHとする。水受キャップ6の第1ピボットホルダ1への組み付け状態における傘部42と取付脚22との間の寸法をDとする。本実施形態では、上記移動距離Lよりも上記挿入突起45の貫通部25内までの長さが長く設定されている。詳細には、挿入突起45の突出高さHは、傘部42と取付脚22との間の寸法Dと、ボス部41の先端と第2のワッシャ52との間の距離Lとの和よりも大きく設定されている(H>D+L)。すなわち、第1水受キャップ6が移動距離Lだけ移動しても挿入突起45が貫通部25内に配置されるように挿入突起45の突出高さHが設定されている。これにより、上記第1ピボットホルダ1に対する第1水受キャップ6の周方向X2への回転をより確実に抑制することができる。 Next, the operation of this embodiment will be described.
Thesecond washer 52 is fixed to the outer periphery of the first pivot shaft 4 by the first washer 51 and the pivot support portion 21. The boss portion 41 of the first water receiving cap 6 overlaps the second washer 52 in the axial direction X1. Therefore, the second washer 52 prevents the first water receiving cap 6 from coming off from the distal end side of the pivot support portion 21. And the insertion protrusion 45 provided in the umbrella part 42 of the 1st water receiving cap 6 is engaged with the penetration part 25 in the circumferential direction X2 by being inserted in the penetration part 25 of the attachment leg 22. Therefore, the first water receiving cap 6 is prevented from rotating in the circumferential direction X <b> 2 with respect to the first pivot holder 1 by the insertion protrusion 45 inserted into the through portion 25. Here, the movement distance of the first water receiving cap 6 from the state in which the lower end of the boss portion 41 is in contact with the mounting leg 22 until the tip of the boss portion 41 is in contact with the second washer 52 is L. In other words, the distance L is the distance between the tip of the boss 41 and the second washer 52 when the lower end of the boss 41 abuts the mounting leg 22. The protrusion height from the umbrella part 42 of the insertion protrusion 45 is set to H. The dimension between the umbrella part 42 and the attachment leg 22 in the assembly state of the water receiving cap 6 to the first pivot holder 1 is defined as D. In this embodiment, the length of the insertion protrusion 45 to the inside of the through portion 25 is set longer than the movement distance L. Specifically, the protrusion height H of the insertion protrusion 45 is based on the sum of the dimension D between the umbrella portion 42 and the mounting leg 22 and the distance L between the tip of the boss portion 41 and the second washer 52. Is also set large (H> D + L). That is, the protrusion height H of the insertion protrusion 45 is set so that the insertion protrusion 45 is disposed in the through portion 25 even if the first water receiving cap 6 moves by the movement distance L. Thereby, rotation to the circumferential direction X2 of the 1st water receiving cap 6 with respect to the said 1st pivot holder 1 can be suppressed more reliably.
第2のワッシャ52は、第1のワッシャ51とピボット支持部21とによって第1ピボット軸4の外周に固定されている。第1水受キャップ6のボス部41は、第2のワッシャ52と軸方向X1に重なっている。そのため、ピボット支持部21の先端側から第1水受キャップ6が抜けることが、当該第2のワッシャ52によって阻止される。そして、第1水受キャップ6の傘部42に設けられた挿入突起45は、取付脚22の貫通部25に挿入されることにより、周方向X2において同貫通部25に係合している。そのため、貫通部25に挿入された挿入突起45によって、第1ピボットホルダ1に対して第1水受キャップ6が周方向X2に回転することが阻止される。なお、ここで、ボス部41の下端が取付脚22に当接した状態からボス部41の先端が第2のワッシャ52に当接するまでの第1水受キャップ6の移動距離をLとする。言い換えると、距離Lは、ボス部41の下端が取付脚22に当接するときのボス部41の先端と第2のワッシャ52との間の距離である。挿入突起45の傘部42からの突出高さをHとする。水受キャップ6の第1ピボットホルダ1への組み付け状態における傘部42と取付脚22との間の寸法をDとする。本実施形態では、上記移動距離Lよりも上記挿入突起45の貫通部25内までの長さが長く設定されている。詳細には、挿入突起45の突出高さHは、傘部42と取付脚22との間の寸法Dと、ボス部41の先端と第2のワッシャ52との間の距離Lとの和よりも大きく設定されている(H>D+L)。すなわち、第1水受キャップ6が移動距離Lだけ移動しても挿入突起45が貫通部25内に配置されるように挿入突起45の突出高さHが設定されている。これにより、上記第1ピボットホルダ1に対する第1水受キャップ6の周方向X2への回転をより確実に抑制することができる。 Next, the operation of this embodiment will be described.
The
また、ワイパ装置の第1水受キャップ6組付け時には、ピボット支持部21にボス部41を外挿し、貫通部25に挿入突起45を軸方向X1から挿入する。このとき、挿入突起45は、貫通部25に挿入されるのみで、軸方向X1には取付脚22に係合しない(軸方向X1に引っ掛かりを有しない)。そして、ピボット支持部21に支持された第1ピボット軸4の外周に第1及び第2のワッシャ51,52を固定することにより、第1水受キャップ6は第1ピボットホルダ1から抜けることが防止されるとともに同第1ピボットホルダ1に対する周方向X2の回転が規制された状態に組み付けられる。従って、第1水受キャップ6が第1ピボットホルダ1から軸方向に抜けることを防止するための構成や、第1ピボットホルダ1に対して周方向X2に第1水受キャップ6が回転することを阻止するための構成が、ワイパ装置の組付け時に損傷されることが抑制される。
Further, when the first water receiving cap 6 of the wiper device is assembled, the boss portion 41 is extrapolated to the pivot support portion 21 and the insertion protrusion 45 is inserted into the through portion 25 from the axial direction X1. At this time, the insertion protrusion 45 is only inserted into the penetrating portion 25 and does not engage with the mounting leg 22 in the axial direction X1 (there is no catch in the axial direction X1). Then, by fixing the first and second washers 51, 52 to the outer periphery of the first pivot shaft 4 supported by the pivot support portion 21, the first water receiving cap 6 may come out of the first pivot holder 1. The rotation is prevented and the rotation in the circumferential direction X2 with respect to the first pivot holder 1 is assembled in a restricted state. Therefore, the structure for preventing the first water receiving cap 6 from coming off from the first pivot holder 1 in the axial direction and the first water receiving cap 6 rotating in the circumferential direction X2 with respect to the first pivot holder 1. It is suppressed that the structure for preventing this is damaged when the wiper device is assembled.
なお、第2ピボット軸7を回動自在に支持した第2ピボットホルダ2、及び同第2ピボットホルダ2に装着された第2水受キャップ9についても同様の作用が得られる。
次に、本実施形態の利点を記載する。 The same action can be obtained for thesecond pivot holder 2 that rotatably supports the second pivot shaft 7 and the second water receiving cap 9 attached to the second pivot holder 2.
Next, advantages of the present embodiment will be described.
次に、本実施形態の利点を記載する。 The same action can be obtained for the
Next, advantages of the present embodiment will be described.
(1)第1ピボットホルダ1から第1水受キャップ6が抜けること、並びに、第2ピボットホルダ2から第2水受キャップ9が抜けることをより確実に防止することができる。また、第1ピボットホルダ1に対して周方向X2に第1水受キャップ6が回転すること、並びに、第2ピボットホルダ2に対して第2ピボット軸7の周方向に第2水受キャップ9が回転することがより効果的に阻止される。これにより、第1ピボットホルダ1から第1水受キャップ6が正規の取付状態から外れること、並びに、第2ピボットホルダ2から第2水受キャップ9が正規の取付状態から外れることをより確実に防止することができる。
(1) It is possible to more reliably prevent the first water receiving cap 6 from being removed from the first pivot holder 1 and the second water receiving cap 9 from being removed from the second pivot holder 2. Further, the first water receiving cap 6 rotates in the circumferential direction X <b> 2 with respect to the first pivot holder 1, and the second water receiving cap 9 in the circumferential direction of the second pivot shaft 7 with respect to the second pivot holder 2. Is more effectively prevented from rotating. As a result, the first water receiving cap 6 is removed from the normal mounting state from the first pivot holder 1 and the second water receiving cap 9 is released from the normal mounting state from the second pivot holder 2 more reliably. Can be prevented.
(2)第1ピボットホルダ1が金属製であり、同第1ピボットホルダ1に装着される第1水受キャップ6が樹脂製であっても、第1水受キャップ6が第1ピボットホルダ1から抜けることを防止するための構成がワイパ装置の組付け時に損傷されることは抑制される。従って、金属製の第1ピボットホルダ1及び樹脂製の第1水受キャップ6を備えた当該ワイパ装置であっても、第1ピボットホルダ1に対する第1水受キャップ6の正規の取付状態からの外れをより確実に防止することができる。第2ピボットホルダ2及び第2水受キャップ9についても同様である。
(2) Even if the first pivot holder 1 is made of metal and the first water receiving cap 6 attached to the first pivot holder 1 is made of resin, the first water receiving cap 6 is made of the first pivot holder 1. It is suppressed that the structure for preventing the removal from being damaged is damaged when the wiper device is assembled. Therefore, even in the wiper device including the first pivot holder 1 made of metal and the first water receiving cap 6 made of resin, the first water receiving cap 6 is attached to the first pivot holder 1 from the normal mounting state. Detachment can be prevented more reliably. The same applies to the second pivot holder 2 and the second water receiving cap 9.
(3)第2のワッシャ52は、第1のワッシャ51とピボット支持部21とによって第1ピボット軸4の軸方向X1に移動不能に配置されている。第1水受キャップ6のボス部41は、第2のワッシャ52と軸方向X1に対向している。そのため、ピボット支持部21の先端側から第1水受キャップ6が抜けることが、当該第2のワッシャ52によって阻止される。従って、本実施形態のワイパ装置では、第1ピボット軸4の外周に固定された第2のワッシャ52によって、第1ピボットホルダ1から第1水受キャップ6が抜けることをより確実に防止することができる。第2ピボット軸7でも同様の利点が得られる。
(3) The second washer 52 is disposed so as not to move in the axial direction X1 of the first pivot shaft 4 by the first washer 51 and the pivot support portion 21. The boss portion 41 of the first water receiving cap 6 faces the second washer 52 in the axial direction X1. Therefore, the second washer 52 prevents the first water receiving cap 6 from coming off from the distal end side of the pivot support portion 21. Therefore, in the wiper device of this embodiment, the second washer 52 fixed to the outer periphery of the first pivot shaft 4 can more reliably prevent the first water receiving cap 6 from coming off from the first pivot holder 1. Can do. Similar advantages can be obtained with the second pivot shaft 7.
(4)挿入突起45は、傘部42から挿入突起45の先端に向けて先細状に形成されている。そのため、ピボットホルダ1に軸方向に沿って水受キャップ6を組み付ける際に、取付脚22の貫通部25に対して挿入突起45が周方向X2に多少ずれていても、貫通部25に挿入突起45が深く挿入されるにつれてずれが修正されて取付脚22と水受キャップ6とが所定の対向状態にセットされる。第2ピボット軸7でも同様の利点が得られる。
(4) The insertion protrusion 45 is formed in a tapered shape from the umbrella portion 42 toward the tip of the insertion protrusion 45. Therefore, when the water receiving cap 6 is assembled to the pivot holder 1 along the axial direction, even if the insertion protrusion 45 is slightly displaced in the circumferential direction X2 with respect to the penetration part 25 of the mounting leg 22, the insertion protrusion 25 is inserted into the penetration part 25. The shift is corrected as 45 is inserted deeply, and the mounting leg 22 and the water receiving cap 6 are set in a predetermined facing state. Similar advantages can be obtained with the second pivot shaft 7.
なお、上記実施形態は、以下のように変更してもよい。
・上記実施形態では、第1ピボット軸4の外周には歯付きワッシャである第1のワッシャ51が締着固定され、第1ピボット軸4に挿通(外挿)された第2のワッシャ52が第1のワッシャ51及びピボット支持部21によって軸方向X1に移動不能に配置されている。しかし、ピボット支持部21の先端から突出した第1ピボット軸4の外周に組み付けられるワッシャの数は、2つに限らず、1つ、もしくは3つ以上であってもよい。例えば、第2のワッシャ52を省略して、歯付きワッシャである第1のワッシャ51のみが第1ピボット軸4の外周に固定された構成としてもよい。この場合、第1のワッシャ51は、ボス部41の少なくとも一部と軸方向X1に重なる。このようにしても、上記実施形態の(1),(2)と同様の利点を得ることができる。なお、第2ピボットホルダ2のピボット支持部21の先端部から突出した第2ピボット軸7の外周に組み付けられるワッシャについても同様に変更してもよい。 In addition, you may change the said embodiment as follows.
In the above embodiment, thefirst washer 51 as a toothed washer is fastened and fixed to the outer periphery of the first pivot shaft 4, and the second washer 52 inserted (extrapolated) through the first pivot shaft 4 is provided. The first washer 51 and the pivot support portion 21 are disposed so as not to move in the axial direction X1. However, the number of washers assembled on the outer periphery of the first pivot shaft 4 protruding from the tip of the pivot support portion 21 is not limited to two, and may be one, or three or more. For example, the second washer 52 may be omitted, and only the first washer 51 that is a toothed washer may be fixed to the outer periphery of the first pivot shaft 4. In this case, the first washer 51 overlaps at least a part of the boss portion 41 in the axial direction X1. Even if it does in this way, the same advantage as (1) and (2) of the above-mentioned embodiment can be acquired. In addition, you may change similarly about the washer assembled | attached on the outer periphery of the 2nd pivot axis | shaft 7 protruded from the front-end | tip part of the pivot support part 21 of the 2nd pivot holder 2. FIG.
・上記実施形態では、第1ピボット軸4の外周には歯付きワッシャである第1のワッシャ51が締着固定され、第1ピボット軸4に挿通(外挿)された第2のワッシャ52が第1のワッシャ51及びピボット支持部21によって軸方向X1に移動不能に配置されている。しかし、ピボット支持部21の先端から突出した第1ピボット軸4の外周に組み付けられるワッシャの数は、2つに限らず、1つ、もしくは3つ以上であってもよい。例えば、第2のワッシャ52を省略して、歯付きワッシャである第1のワッシャ51のみが第1ピボット軸4の外周に固定された構成としてもよい。この場合、第1のワッシャ51は、ボス部41の少なくとも一部と軸方向X1に重なる。このようにしても、上記実施形態の(1),(2)と同様の利点を得ることができる。なお、第2ピボットホルダ2のピボット支持部21の先端部から突出した第2ピボット軸7の外周に組み付けられるワッシャについても同様に変更してもよい。 In addition, you may change the said embodiment as follows.
In the above embodiment, the
・第2のワッシャ52の形状は、上記実施形態の形状に限らない。例えば、図4に示す第2のワッシャ72は、ボス部41の外周で径方向X3に同ボス部41と重なる位置まで軸方向X1に筒状に延びており、ボス部41の先端が第2のワッシャ72の内側に収容される。このようにすると、ボス部41の内側に水等の液体が浸入することが第2のワッシャ72によって抑制される。
The shape of the second washer 52 is not limited to the shape of the above embodiment. For example, the second washer 72 shown in FIG. 4 extends in a cylindrical shape in the axial direction X1 up to a position overlapping with the boss 41 in the radial direction X3 on the outer periphery of the boss 41, and the tip of the boss 41 is the second. Is accommodated inside the washer 72. In this way, the second washer 72 prevents the liquid such as water from entering the boss portion 41.
また、図5に示すように、第2のワッシャ72におけるボス部41と径方向X3に重なる部分に第1係合部81を設けてもよい。この場合、当該第1係合部81と軸方向X1に係合する第2係合部82をボス部41に設ける。図5に示す例では、第1係合部81は、第2のワッシャ72を径方向に貫通した貫通孔であり、第2係合部82は、ボス部41の外周面から径方向外側に突出し第1係合部81に挿入された突起である。そして、第1係合部81と第2係合部82とは凹凸係合している。なお、第1係合部81を第2のワッシャ72から径方向内側に突出した突起とし、第2係合部82をボス部41の外周面に設けられた凹部もしくはボス部41を径方向に貫通した貫通孔としてもよい。このようにすると、第1係合部81に第2係合部82が軸方向X1に係合することにより、第2のワッシャ72に対する第1水受キャップ6の軸方向X1の移動が抑制され、ひいては、第1ピボットホルダ1に対する第1水受キャップ6の軸方向X1の移動が抑制される。従って、第1水受キャップ6の軸方向X1の振動や、第1水受キャップ6の軸方向X1の移動に起因する騒音の発生を抑制することができる。
Further, as shown in FIG. 5, a first engagement portion 81 may be provided in a portion overlapping the boss portion 41 and the radial direction X3 in the second washer 72. In this case, the boss portion 41 is provided with a second engagement portion 82 that engages with the first engagement portion 81 in the axial direction X1. In the example shown in FIG. 5, the first engaging portion 81 is a through-hole penetrating the second washer 72 in the radial direction, and the second engaging portion 82 is radially outward from the outer peripheral surface of the boss portion 41. A protrusion that protrudes and is inserted into the first engaging portion 81. And the 1st engaging part 81 and the 2nd engaging part 82 are carrying out uneven | corrugated engagement. The first engaging portion 81 is a protrusion protruding radially inward from the second washer 72, and the second engaging portion 82 is a recess provided on the outer peripheral surface of the boss portion 41 or the boss portion 41 in the radial direction. It is good also as a through-hole penetrated. If it does in this way, the movement of the 1st water receiving cap 6 with respect to the 2nd washer 72 in the axial direction X1 will be suppressed by the 2nd engaging part 82 engaging with the 1st engaging part 81 in the axial direction X1. As a result, the movement of the first water receiving cap 6 in the axial direction X1 with respect to the first pivot holder 1 is suppressed. Therefore, it is possible to suppress the occurrence of noise due to the vibration of the first water receiving cap 6 in the axial direction X1 and the movement of the first water receiving cap 6 in the axial direction X1.
また、図6に示すように、ボス部41の先端部と第2のワッシャ72とがインロー嵌合するようにボス部41と第2のワッシャ72とを構成してもよい。図6に示す例では、ボス部41の先端部に、同ボス部41の外径を小さくすることにより設けられた段差凹部83が設けられている。そして、第2のワッシャ72におけるボス部41と径方向X3に重なる部分は、ボス部41の段差凹部83に外嵌されている。即ち、第2のワッシャ72の先端部(第2のワッシャ72における第1ピボット軸4の基端側を向いた下端部)とボス部41の先端部とが、インロー嵌合している。従って、第2のワッシャ72の先端部とボス部41の先端部との間に形成された迷路構造により、ボス部41の内側に水等の液体が浸入することがより抑制される。なお、第2のワッシャ72の先端部にボス部41の先端部が外嵌された構成としてもよい。
Further, as shown in FIG. 6, the boss portion 41 and the second washer 72 may be configured so that the tip portion of the boss portion 41 and the second washer 72 are fitted together. In the example shown in FIG. 6, a stepped recess 83 provided by reducing the outer diameter of the boss 41 is provided at the tip of the boss 41. A portion of the second washer 72 that overlaps the boss portion 41 in the radial direction X <b> 3 is externally fitted to the stepped recess 83 of the boss portion 41. That is, the distal end portion of the second washer 72 (the lower end portion of the second washer 72 facing the proximal end side of the first pivot shaft 4) and the distal end portion of the boss portion 41 are inlay-fitted. Therefore, the maze structure formed between the distal end portion of the second washer 72 and the distal end portion of the boss portion 41 further suppresses the entry of liquid such as water into the boss portion 41. Note that the tip end portion of the boss 41 may be externally fitted to the tip end portion of the second washer 72.
第2ピボット軸7の外周に固定される第2のワッシャ52及び第2水受キャップ9についても、図4乃至図6に示した例と同様に変更してもよい。また、第1のワッシャ51を、図4乃至図6に示した第2のワッシャ72のように構成してもよい。
The second washer 52 and the second water receiving cap 9 fixed to the outer periphery of the second pivot shaft 7 may also be changed in the same manner as in the example shown in FIGS. Further, the first washer 51 may be configured like the second washer 72 shown in FIGS.
・上記実施形態では、第1及び第2ピボットホルダ1,2は金属製であり、第1及び第2水受キャップ6,9は樹脂製である。しかしながら、第1及び第2ピボットホルダ1,2を構成する材料、及び、第1及び第2水受キャップ6,9を構成する材料はこれに限らない。例えば、第1及び第2水受キャップ6,9は、金属製もしくはゴム製であってもよい。
In the above embodiment, the first and second pivot holders 1 and 2 are made of metal, and the first and second water receiving caps 6 and 9 are made of resin. However, the material constituting the first and second pivot holders 1 and 2 and the material constituting the first and second water receiving caps 6 and 9 are not limited thereto. For example, the first and second water receiving caps 6 and 9 may be made of metal or rubber.
・上記実施形態の挿入突起45に代えて、図7及び図8に示す一対の突起としての係止突起91を第1水受キャップ6の傘部42に備えてもよい。一対の係止突起91は、傘部42から取付脚22の周方向X2の両隣の領域に向けて軸方向X1に突出しており、取付脚22の周方向X2の両隣の領域で同取付脚22とそれぞれ周方向X2において対向している。即ち、取付脚22は、一対の係止突起91の間に配置され、当該一対の係止突起91と軸方向X1には係合することなく周方向X2に係合している。
In place of the insertion protrusion 45 of the above embodiment, a locking protrusion 91 as a pair of protrusions shown in FIGS. 7 and 8 may be provided on the umbrella portion 42 of the first water receiving cap 6. The pair of locking projections 91 protrude in the axial direction X1 from the umbrella portion 42 toward both adjacent regions in the circumferential direction X2 of the mounting leg 22, and the same mounting leg 22 in both adjacent regions in the circumferential direction X2 of the mounting leg 22. Are opposed to each other in the circumferential direction X2. That is, the mounting leg 22 is disposed between the pair of locking protrusions 91 and is engaged with the pair of locking protrusions 91 in the circumferential direction X2 without being engaged in the axial direction X1.
このようにすると、係止突起91によって、第1ピボットホルダ1に対して第1水受キャップ6が周方向X2に回転することが阻止される。また、ワイパ装置の組付け時には、ピボット支持部21にボス部41を外挿し、係止突起91を軸方向X1から取付脚22の周方向X2の両隣の領域に配置する。このとき、各係止突起91は、軸方向X1には取付脚22に係合しない。その後、ピボット支持部21に支持された第1ピボット軸4の外周に第1及び第2のワッシャ51,52を固定することにより、第1水受キャップ6は第1ピボットホルダ1から抜けることが防止されるとともに同第1ピボットホルダ1に対する周方向X2の回転が規制された状態に組み付けられる。従って、第1水受キャップ6が第1ピボットホルダ1から軸方向に抜けることを防止するための構成や、第1ピボットホルダ1に対して周方向X2に第1水受キャップ6が回転することを阻止するための構成が、ワイパ装置の組付け時に損傷されることが抑制される。よって、当該ワイパ装置では、第1ピボットホルダ1から第1水受キャップ6が抜けることをより確実に防止することができる。この例においても上記実施形態と同様に、係止突起91の突出高さHは、傘部42と取付脚22との間の寸法Dと、ボス部41の先端と第2のワッシャ52との間の距離Lとの和よりも大きく設定されている。すなわち、第1水受キャップ6が移動距離Lだけ移動しても係止突起91と取付脚22との周方向X2における係合が外れないように係止突起91の突出高さHが設定されている。したがって、第1ピボットホルダ1に対して周方向X2に第1水受キャップ6が回転することがより効果的に阻止される。これにより、第1ピボットホルダ1から第1水受キャップ6が正規の取付状態から外れることをより確実に防止することができる。
In this manner, the locking projection 91 prevents the first water receiving cap 6 from rotating in the circumferential direction X2 with respect to the first pivot holder 1. Further, when the wiper device is assembled, the boss portion 41 is extrapolated to the pivot support portion 21, and the locking projections 91 are disposed in both adjacent regions from the axial direction X 1 to the circumferential direction X 2 of the mounting leg 22. At this time, each locking projection 91 does not engage with the mounting leg 22 in the axial direction X1. Thereafter, by fixing the first and second washers 51 and 52 to the outer periphery of the first pivot shaft 4 supported by the pivot support portion 21, the first water receiving cap 6 may come out of the first pivot holder 1. The rotation is prevented and the rotation in the circumferential direction X2 with respect to the first pivot holder 1 is assembled in a restricted state. Therefore, the structure for preventing the first water receiving cap 6 from coming off from the first pivot holder 1 in the axial direction and the first water receiving cap 6 rotating in the circumferential direction X2 with respect to the first pivot holder 1. It is suppressed that the structure for preventing this is damaged when the wiper device is assembled. Therefore, in the wiper device, it is possible to more reliably prevent the first water receiving cap 6 from coming off from the first pivot holder 1. Also in this example, as in the above embodiment, the protrusion height H of the locking projection 91 is determined by the dimension D between the umbrella portion 42 and the mounting leg 22, the tip of the boss portion 41, and the second washer 52. It is set larger than the sum of the distance L between them. That is, the protrusion height H of the locking protrusion 91 is set so that the engagement of the locking protrusion 91 and the mounting leg 22 in the circumferential direction X2 is not disengaged even if the first water receiving cap 6 moves by the moving distance L. ing. Therefore, the first water receiving cap 6 is more effectively prevented from rotating in the circumferential direction X2 with respect to the first pivot holder 1. Thereby, it can prevent more reliably that the 1st water receiving cap 6 remove | deviates from the regular attachment state from the 1st pivot holder 1. FIG.
なお、傘部42に設けられた係止突起91の数は、取付脚22の周方向X2の両隣の領域にそれぞれ係止突起91が配置されるのであれば、一対に限らず、適宜変更してもよい。また、第2水受キャップ9についても同様に、挿入突起45に代えて係止突起91を備えてもよい。
Note that the number of the locking protrusions 91 provided on the umbrella part 42 is not limited to a pair and may be changed as appropriate as long as the locking protrusions 91 are respectively disposed in the adjacent regions of the mounting leg 22 in the circumferential direction X2. May be. Similarly, the second water receiving cap 9 may include a locking protrusion 91 instead of the insertion protrusion 45.
・図7の例における第2のワッシャ52は、図4に示す第2のワッシャ72と同様に、ボス部41の外周で径方向X3に同ボス部41と重なる位置まで軸方向X1に筒状に延びていてもよい。これにより、ボス部41の先端が第2のワッシャ52の内側に収容される。
The second washer 52 in the example of FIG. 7 is cylindrical in the axial direction X1 to the position where it overlaps with the boss 41 in the radial direction X3 on the outer periphery of the boss 41, like the second washer 72 shown in FIG. It may extend to. As a result, the tip of the boss portion 41 is accommodated inside the second washer 52.
・上記実施形態では、貫通部25は、取付脚22を軸方向X1に貫通した円形状の貫通孔である。しかしながら、貫通部25の形状はこれに限らない。例えば、貫通部25は、軸方向X1から見た形状が楕円形状、多角形状等をなす貫通孔であってもよい。また、貫通部25は、取付脚22を軸方向X1に貫通し、且つ取付脚22に対する挿入突起45の周方向X2の移動(周方向X2の一方側への移動と他方側への移動との両方の移動)を規制可能な形状であれば、貫通孔に限らず、溝状をなすものであってもよい。例えば、貫通部25は、取付脚22の周方向X2の一端から取付脚22の周方向X2の中央に向けて周方向X2に延びた後に径方向X3に延びる略L字状の溝であってもよい。また例えば、貫通部25は、軸方向X1から見て、取付脚22の周方向X2の一端から径方向X3に対して傾斜した方向に沿って延びる溝であってもよい。
In the above embodiment, the through portion 25 is a circular through hole that penetrates the mounting leg 22 in the axial direction X1. However, the shape of the penetration part 25 is not restricted to this. For example, the through portion 25 may be a through hole whose shape viewed from the axial direction X1 is an elliptical shape, a polygonal shape, or the like. Further, the penetrating portion 25 penetrates the mounting leg 22 in the axial direction X1 and moves the insertion projection 45 with respect to the mounting leg 22 in the circumferential direction X2 (movement of the circumferential direction X2 to one side and movement to the other side). As long as it is a shape that can regulate both movements), the shape is not limited to the through hole, and may be a groove shape. For example, the penetrating portion 25 is a substantially L-shaped groove extending from the one end of the mounting leg 22 in the circumferential direction X2 toward the center of the mounting leg 22 in the circumferential direction X2 and then extending in the radial direction X3. Also good. Further, for example, the through portion 25 may be a groove extending from one end in the circumferential direction X2 of the mounting leg 22 along a direction inclined with respect to the radial direction X3 when viewed from the axial direction X1.
・上記実施形態では、第1水受キャップ6の傘部42は、1つの挿入突起45を備え、取付脚22は、当該挿入突起45が挿入される貫通部25を1つ備えている。しかしながら、傘部42に設けられた挿入突起45の数、及び取付脚22に設けられた貫通部25の数は、複数であってもよい。第2ピボットホルダ2及び第2水受キャップ9についても同様である。
In the above embodiment, the umbrella part 42 of the first water receiving cap 6 includes one insertion protrusion 45, and the mounting leg 22 includes one penetration part 25 into which the insertion protrusion 45 is inserted. However, the number of the insertion protrusions 45 provided on the umbrella part 42 and the number of the through parts 25 provided on the mounting leg 22 may be plural. The same applies to the second pivot holder 2 and the second water receiving cap 9.
・第1ピボットホルダ1及び第2ピボットホルダ2は、筒状のピボット支持部と、当該ピボット支持部から径方向外側に突出した取付脚とを有するのであれば、上記実施形態の形状に限らず、車両への搭載レイアウトスペースや搭載姿勢に応じて変更されてもよい。
